RS(255, 239) with Erasures

For the RS(255, 239) code with erasure correction capability, the maximum number of correctable errors only is 8, and the maximum number of correctable erasures only is 16. When the number of erasures plus two times the number of errors is less than 16, both the errors and the erasures can be corrected. Resource usage and performance parameters for the decoder are listed in Table 1.
